Problems solved by technology

Although these methods have improved the stability of superhydrophobic fabrics to a certain extent, they still need to go through multiple steps such as fabric surface activation, ray irradiation, and low surface energy modification, which not only affect the strength and appearance of the fabric, but also complicate the process. Severely limit the practical application of superhydrophobic fabrics

Abstract

The invention discloses an organic silicon polymer super-hydrophobic textile finishing agent. The organic silicon polymer super-hydrophobic textile finishing agent is prepared by adding organic silicon and organic silane into an alkaline alcohol-water solution and carrying out hydrolytic condensation. The organic silicon polymer super-hydrophobic textile finishing agent contains a hydrophobic group and a coupling group; and in dip-coating and high-temperature curing processes, the coupling group can be chemically bonded with fibers of a textile and the hydrophobic group has a super-hydrophobiceffect. The textile is dipped and coated in an organic silicon textile finishing agent solution which is diluted for 5 to 10 times for 2 to 10min and then is cured at 80 to 180 DEG C for 2 to 10min to obtain the super-hydrophobic textile. The super-hydrophobic textile disclosed by the invention has the advantages of excellent super-hydrophobic performance, washing resistance and the like and canbe used for constructing various super-hydrophobic textiles; and the textile does not need to be pre-treated, so that a preparation technology is extremely simplified, and properties including intrinsic mechanical strength, flexibility, luster, hand feeling and the like are kept.

Description

Technical field [0001] The invention relates to a preparation method of a superhydrophobic fabric finishing agent, in particular to a preparation and a use method of an organosilicon polymer superhydrophobic fabric finishing agent. Background technique [0002] The lotus leaf has the characteristics of silt and not staining. Inspired by the lotus leaf effect, superhydrophobic surfaces have received widespread attention. Super-hydrophobic surface refers to a surface where the contact angle of water droplets is greater than 150° and the rolling angle is low. It has excellent self-cleaning performance and has broad application prospects in self-cleaning textiles, oil-water separation, anti-corrosion, anti-icing and other fields. The study of superhydrophobic surfaces has aroused widespread interest. [0003] Textiles are closely related to people's production and life. The research and development of functional textiles has received more and more attention, which has greatly improv...
